The objective of this study was to evaluate the present conventional selection program of a swine nucleus farm and compare it with a new selection strategy employing genomic enhanced breeding value (GEBV) as the selection criteria. The ZPLAN+ software was employed to calculate and compare the genetic gain, total cost, return and profit of each selection strategy. The first strategy reflected th...
Artificial insemination technique and semen preparation impact boar utilization efficiency, genetic dissemination, and biosecurity. Intrauterine (IUI) and deep intrauterine (DUI) AI techniques require lower number of spermatozoa per dose compared to conventional (CON) AI. Frozen semen (FRO) has been associated with lower reproductive performance compared to fresh semen (FRE) preparation. The co...
زمینه مطالعاتی: در کشورهای در حال توسعه مخصوصا" ایران سرمایههای بومی نقش مهمی در اقتصاد روستایی ایفا میکنند. نژادهای بومی در مقایسه با سویههای تجاری میتوانند سطوح بالاتری از عملکرد را در شرایط نامساعد محیطی حفظ کنند. هدف: این مطالعه به منظورمقایسه راهکارهای انتخاب ژنومی و انتخاب کلاسیک در طیور بومی ایران با استفاده از نرمافزار ZPLAN+ انجام شد. روش کار: یک سناریوی مرجع و یک سناریوی ژنومی ...
The study simulated different potential breeding programs to design the optimal structure and operational management for Borana goat. It evaluated scenarios using ZPLAN+ software maximize genetic gain, discounted profit determine optimum size of base population a community-based program (CBBP) nucleus. analyzed combinations objective traits in index, assessed effect changing buck doe ratio, imp...
Improving feed efficiency in dairy cattle could result in more profitable and environmentally sustainable dairy production through lowering feed costs and emissions from dairy farming. In addition, beef production based on dairy herds generates fewer greenhouse gas emissions per unit of meat output than beef production from suckler cow systems. Different scenarios were used to assess the profit...
The development of genomic selection has created new strategies in animal breeding programs. The aim of this study was to investigate the efficiency of genomic selection in breeding programs of native hens. In this study, a reference scenario with 3380 birds using pedigree and phenotypic information was simulated and the expected genetic progress was derived deterministically with the software ...
